TECHNICAL FIELD

The disclosure relates to children's products, and particularly to a child safety seat.

BACKGROUND

In order to improve the safety performance of a child when he is sitting in a car, generally, a child safety seat is installed on a car seat. Among them, the 360-degree rotatable child safety seats are favored by many people for their cool appearances and simple operations. In order to further transmit the information of the rotation angle of the child safety seat directly to the user, most of the 360-degree rotatable child safety seats are provided with several electrical devices to achieve this purpose. However, since most of the electrical devices are electrically connected to each other by electrical cables, which will cause the cables to rotate with the rotation of the child safety seats, and in turn causes cable winding. Over time, the service life of electrical devices will be greatly reduced; thus, causing an unfavorable experience to the users.

In order to solve the shortcomings of the related art, there is a need for a rotatable child safety seat that can avoid cable winding.

DETAILED DESCRIPTION

In order to describe the technical content and structural features of the disclosure in more detail, the following detailed illustration is provided conjunction with the embodiments and the accompanying drawings.

Referring to FIGS. 1-2 , a child safety seat 100 according to the disclosure comprises a base 11 and a body 12 rotatably connected to the base 11 for providing a seating space. The base 11 is rotatably connected to the body 12 by a rotating shaft 13. In order to prevent cables connected between electrical devices of the child safety seat 100 from moving along with a rotation of the base 11 and the body 12, the child safety seat 100 according to the disclosure further comprises an electrical pivoting structure 14. The electrical pivoting structure 14 includes a base pivoting member 141 for electrically connecting to a base electrical device (not shown in FIGS. 1-2 ) in the base 11, and a body pivoting member 142 for electrically connecting to a body electrical device (not shown in FIGS. 1-2 ) in the body 12. Wherein, the base pivoting member 141 is coupled (for example fixedly connected) to the base 11, and the body pivoting member 142 is coupled to the body 12. The base pivoting member 141 has a base conductive part 1411, and the body pivoting member 142 has a body conductive part 1421. The base conductive part 1411 and the body conductive part 1421 are rotatably and electrically connected in the rotating shaft 13. The electrical connection between the base conductive part 1411 and the body conductive part 1421 makes the base electrical device be electrically connected to the body electrical device. When the child safety seat 100 according to the disclosure rotates, the base conductive part 1411 and the body conductive part 1421 will rotate with the rotation of the base 11 and the body 12. Since the body pivoting member 142 is coupled to the body 12, and the base pivoting member 141 is coupled to the base 11, the body pivoting member 142 is in a stationary state in respect to the body electrical device, and the base pivoting member 141 is also in a stationary state in respect to the base electrical device. On the one hand, the base electrical device and the body electrical device are coupled to each other by the electrical pivoting structure 14, since there is no cable between the base electrical device and the body electrical device, cable winding will not occur, which can completely solve the winding problem caused by the use of cables in the prior art. On the other hand, the body electrical device and the body pivoting member 142 are electrically connected to each other by a cable, the base electrical device and the base pivoting member 141 are also electrically connected to each other by a cable, such that the body pivoting member 142 is in a static state in respect to the body electrical device, and the base pivoting member 141 is also in a static state in respect to the base electrical device. Both the cable connected between the body pivoting member 142 and the body electrical device and the cable coupled between the base pivoting member 141 and the base electrical device are stationary, that is, the cables will not move with the rotation of the child safety seat 100, and will not be winded. In this way, the problem of winding caused by the use of cables in the related art may be completely solved. Therefore, the child safety seat 100 according to the disclosure is totally different from that in the related art in which the electrical devices are electrically connected to each other by directly using cables, while based on the present disclosure, the electrical devices are electrically connected to each other by the electrical pivoting structure 14, which is simple in structure and can avoid cable winding, and is suitable for widespread promotion and use.

Referring to FIGS. 2-5 , the base conductive part 1411 and the body conductive part 1421 according to the disclosure form a pluggable structure which is conductive and rotatable. More specifically, the body conductive part 1421 has a conductive depression structure 143, and the base conductive part 1411 has a conductive protrusion structure 144 which may be plugged into and unplugged from the depression structure 143, so the pluggable structure may be formed by the depression structure 143 and the protrusion structure 144. In order to protect the conductor, the depression structure 143 is covered with a first insulating shell 14111, and the base pivoting member 141 under the protrusion structure 144 is covered with a second insulating shell 14211, that is, the protrusion structure 144 is protruded out of the second insulating shell 14211. The protrusion structure 144 may be plugged into and unplugged from the depression structure 143. The depression structure 143 has a depressed seat 1431 at its bottom, and the protrusion structure 144 has a tapered portion 1441 being cooperative with the depressed seat 1431 at its top. The tapered portion 1441 has a chamfered structure, and the chamfered structure has a certain guiding effect, which facilitates plugging the protrusion structure 144 into the depression structure 143. After the protrusion structure 144 is plugged into the depression structure 143, the second insulating shell 14211 and the first insulating shell 14111 are in an abutting contact, and the abutting contact is smooth in structure. Of course, the depression structure 143 may also be disposed on the base conductive part 1411, and the conductive protrusion structure 144 being pluggable in the depression structure 143 may be disposed on the body conductive part 1421.

Referring to FIG. 3 , the rotating shaft 13 connected between the base 11 and the body 12 has a rotating shaft body 131 with a hollow structure. Two ends of the rotating shaft body 131 extend outwardly so as to form a shoulder 1311 respectively, while the body 12 is provided with a mounting hole 15 which is cooperative with the rotating shaft 13 in a position at which the body 12 is rotatably connected to the base 11. The rotating shaft 13 is mounted in the mounting hole 15, and the base conductive part 1411 and the body conductive part 1421 are accommodated in the hollow structure of the rotating shaft 13. Furthermore, in addition to the body conductive part 1421, the body pivoting member 142 also includes a body connecting part 1422 for connecting with the body 12. The plane where the body connecting part 1422 is located is orthogonal to the plane where the body conductive part 1421 is located. Similarly, in addition to the base conductive part 1411, the base pivoting member 141 also includes a base connecting part 1412 for connecting with the base 11. The plane where the base connecting part 1412 is located is orthogonal to the plane where the base conductive part 1411 is located. Such orthogonal arrangement can make rotation of the base conductive part 1411 and the body conductive part 1421 smooth.

Preferably, the body electrical device according to the disclosure may be a detection device for detecting whether a top strap of the body 12 is tightened, and the base electrical device may be an indicator for displaying tightening state information of the top strap. When in use, the user can clearly know whether the top strap is in a tightened state according to the indicator. When the top strap is tightened, the indicator shows green, and when the top strap is in a non-tightened state, the indicator shows red.

It would be noted, specific structures of the base 11 and the body 12 of the child safety seat 100 involved in the disclosure are well known to those skilled in the art, and will not be described in detail here.
